Wrist sprain

The ligament that is usually sprained is the scapho-lunate ligament, which runs between the scaphoid and lunate bones in the wrist. There are a lot of bones in the wrist; so many ligaments are needed to hold them together. Unlike the scapho-lunate ligament, however, these other ligaments are not injured as often. Minor wrist sprains may just stretch the ligament slightly; more serious sprains can actually rupture the ligament. Another frequently torn ligament is the triangular fibrocartilage complex or TFCC. This ligament is a stabilizer of the ulnar side of the wrist and is a cause of ulnar sided wrist pain.

What causes wrist sprains?

Wrists sprains are a common injury and are often caused by sporting activities or everyday falls. Wrist sprains often occur when the hand is held out to break or cushion a fall and the wrist is bent back upon impact with the ground. In sports such as skiing, snowboarding, or football, sprains are a common injury.

What are the symptoms?

When a sprain occurs, the wrist usually swells up and is rather painful, especially when moved.

How to diagnose it?

If a sprain is suspected, your hand doctor will start off by examining your wrist to see how well it moves, where it hurts, and whether it is stable. To see if there are any fractured bones and how they are positioned, X-rays are usually taken. Additionally, an MRI may be taken to confirm the hand surgeon’s diagnosis.

Functional treatment

If the wrist is sprained, you will likely have a splint or cast placed around it to prevent movement. However, surgery may be a possibility as well. The surgery can be performed in a traditional, open, or arthroscopic manner.

Surgery

If arthroscopic surgery is performed, several small cuts the size of a grain of rice will be made around the wrist and a tiny camera will be inserted through them to examine the bones and ligaments and possibly treat them.

If arthroscopic surgery isn’t an option, open surgery may be needed to repair the injured ligament. Surgery is used if the bones need to be held in place by metal pins, screws, or plates, after which a splint or cast is placed on the wrist to prevent movement that could cause further injury. The splint or cast is usually worn for six to twelve weeks after surgery.

Chronic injuries

If the injury is an old one that happened several months or years ago, it is referred to as a chronic injury. If the cartilage has been damaged and has become arthritic, the symptoms will be much the same as a sprain, and there will be swelling, stiffness, and pain.

Treatment for chronic injuries

To treat this, the ligament may be repaired or restored as if it were a new injury if there is little damage to the cartilage.

Treatment of the arthritis usually starts with splints and anti-inflammatory medications, or even cortisone injections. If these don’t work, surgery may be performed. Your hand surgeon will suggest the best course of treatment for you. For example, a partial or complete wrist fusion, removal of the affected bones, or replacement of the wrist may be suggested.

Even with the best and quickest treatment after the sprain by your hand surgeon, sometimes the wrist remains swollen, stiff, or sore for a long time. This is because of how the wrist is made up and the precise and delicate organization of bones, ligaments, and cartilage that allow it to move. Any injury to that carefully arranged system could affect its fine structure and use.

New treatment to come in the future

Ways to better repair and correct wrist sprains, and the ligaments and other parts of the wrist involved, are constantly being researched.
